I was able to get a brand new Madison on Ebay early this month for under $250.
This was pretty freakish:
The bike was being sold from an LBS that had closed its doors... for $300 +47 shipping.
Microsoft Live.com was offering 25% Cashback if you joined and used their Cashback program:
$300 x .75 = 225 + 47 = $272.
Ebay was also offering $30 if you used a new Ebay Mastercard:
$272 -$30 = $242.00
Live.com is down to 4% these days.
Either way, keep your eyes peeled. The deals do happen.
